Kosovo's opposition says it will begin street protests in an effort to force the government to cancel deals with Serbia and Montenegro after its lawmakers were barred from parliament after using tear gas to end a session.

Deputies from parties in the coalition government met alone on November 30 after their session was disrupted by tear gas yet again.

The opposition had pledged that no parliament sessions will be held until the government renounces a deal with Serbia giving more powers to ethnic-Serb communities in Kosovo as well as an agreement with Montenegro on border demarcation.

The opposition called on people to join it in street protests.

In Brussels, the EU issued a statement calling for a return to dialogue in Kosovo, adding that disruptions of parliament with tear gas "is neither acceptable nor will it solve any problem for the citizens of Kosovo."

Over the past three months, the opposition has regularly disrupted parliament with tear gas, pepper spray, whistles, and water bottles.

U.S. Secretary of State John Kerry is due in Pristina later this week.
